Application filed July 6, 1917.

i To all whom it may concern:

Be it known that I, HILMER N. Eunomr, a citizen of the United States, residing at Burlington, in the county of Des Moines and State of Iowa, have invented certain new and useful Improvements in Molds for WVeatherproof \Vatering-Troughs, of which the following is a specification.

This invention relates to improvements in molding devices whereby tanks and like receptacles of various shapes and sizes may be constructed with hollow Walls, or with walls having dead air spaces therein, and has for one of its objects to provide a device of this character constructed of sheet or plate metal and in separable sections, or partly of metal and partly of wood, and capable of being increased or decreased in size by increasing or'decreasing the number of the sections.

Another object of the invention is to provide a device of this character which may be transported from place to place and employed in constructing tanks or like receptacles where they are to remain permanently, and which may be repeatedly employed for constructing the tanks in any required 10- cality.

WVith these and other objects in view, the invention consists in certain novel features of construction, as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention Figure 1 is a plan view partly in section of one of the improved molds;

The improved device comprises in general an outer shell, an inner shell, an outer intermediate shell and an inner intermediate shell disposed in spaced relation. the space between the outer shell and the outer intermediate shell designed to receive cementitious material and forming the outer wall of the tank or trough, and the space be tween the inner shell and the inner intermediate shell designed to receive cementitious material to form theinner wall of the tank or trough, a dead space between the intermediate shells constituting the air space between the walls of the trough or tank.

The shells are constructed ina plurality of sections engaging and to end, and may be of any required form or shape to conform to the tanks or troughs which it is required to arranged to form an oblong tank having rounded or semi-circular ends, which is the usual form. The terminal portions of the various shells will preferably be constructed of sheet or plate metal as light as possible consistent with the strains to which they will be subjected, and will preferably be galvanized or otherwise protected from corrosion, while the side portions of the shell sections will preferably be of wood in stave form as shown in Fig. 5, or all of the sections may be of wood or all of metal as may be found most advantageous. The outer terminal shell sections are designated by the character 10, while the intermediate outer shell sections are designated by the character 11. The terminal sections of the-outer intermediate shell are designated by the character 12, while the side vsections of the outer intermediate shell are designated by the character 13. The terminal sections of the inner intermediate shell are designated bv the character 14, while the side sections of the inner intermediate shell are designated by the character 15. The terminal sections of the inner shell are designated by the character 16, while the side sections of the'inner shell are designated by the character 17. The various sections 1011 are of the full height of the tank or troughwhich is to be constructed, the outer intermediate shell sections are of less height thanthe outer shell sections, the inner intermediate shellsections are of less height than the outer intermediate shell sections, while the inner shell sections are of the same height asthe inner intermediate shell sections, the reason for these differences in height to be hereafter explained.

The ends of the several side sections next tothe terminal sections are provided with vertical combined guard and holding mem-- bers 18, preferably of L metal, which overlap the joints between the sections. lVhen two or more of the side sections are employed to increase the length of the tank or trough, the adjacent webs of the members 18 are coupled by plates 19 bolted or otherwise secured in place. By furnishing a plurality of the side sections of different widths having the guard members 18 attached, togetherwith a corresponding number of the coupling members 19, tanks or troughs of different lengths may be produced, as will be obvious.

The various sections are also provided .with horizontally directed supporting or bracing ribs 20. The ribs are located upon the outer faces of theouter sections 10-11, upon'the inner faces of the inner sections 16-17, and upon the confronting faces of the intermediate sections 12-13 and 14-15. The ribs 20 abut at their ends against the edges of the members 18. The ribs 20 are -preferably formed of L-bars with one web of each rib' directed laterally from the section to which it is attached, and all of the brace members 18 and ribs 20 are firmly riveted or otherwise secured to the sections. The ribs 20 of the outer and inner sections are coupled near theirends by stays 21 and each stay provided with a clip device 22 to receive the hooked terminal 23 of a binding rod 24, by which the sections are firmly held in position. Each binding rod is provided with a turn-buckle 25, to enable the requisite strain to be imparted to hold the parts tonected at their ends respectively to the stays 26 and to the terminal shell members 10. Depending from the stays 26 are vertical stay members 29 which are bolted or otherwise secured to the intermediate and inner :ections,to hold them in proper spaced posiion.

A'set of the stay devices will be located at each end of the mold apparatus and at as many intermediate points as required, but one set only is shown in Figs. 1 and 2, to avoid obscuring the details of construction. The retaining member upon which the inner bottom member is supported is represented at 30, and is suitably supported by spacer blocks 31 whereby the member 30 is supported in spaced relation to the lower bottom member or base designated at 36. Other spacer blocks 33 are located between the intermediate shell members at their lower ends as shown in Fig. 2. The retaining member which is located over the upper edges of the cementitious side walls is designated by the character 34.

As many of the spacer members 33 may be employed as required and spaced any suitable distance.

\Vith a device thus constructed the various steps required to construct the tank or trough is as follows:

The outer shell sections 10-11 are erected where the tank is to be located with their -lower edges upon the ground and the coupling rods 24 plied.

The required number and sizesof the side members 11, 13, 15 and 17 are employed to form the required size of trough and are connected as above described.

A layer of cementitious material is then deposited upon the ground within the sections 10-11 and leveled off by suitable implements. This layer of material constitutes the outer or lower bottom member 36 of the tank or trough. The outer intermediate sections 12-13 are then erected within the outer shell sections and spaced inwardly therefrom with their lower edges resting upon the bottom member 36. The spacer blocks 33 are then located in position upon the lower bottom member 36 as shown in with their turn-buckles ap- Fig. 2, and the spacer members 31 likewise.

V disposed in position and the retaining member 30 deposited upon the spacer members. The inner intermediate section members 12-13 are then located in position within the outer intermediate shell sections and spaced therefrom and against the spacer blocks 33. The stay members 26 and 28 are then arranged in position and coupled to the outer shell members and the intermediate stay members 29 coupled to the outer intermediate shell members. Another layer ofcementitious material indicated at 32, is then deposited upon the retaining member 30 and leveled off by a suitable implement. The inner section members 16-17 are then located in position and spaced from the inner intermediate sections 11--13. and the stay members 29 coupled thereto. The space between the outer sections 10-11 and the inner intermediate sections 12-13 is then filled with cementitious material and the space between the inner section IbflDbBIS 1517 and the inner intermediate sections 14-15 likewise filled with the cementitious material, the two vertical sections of the material constituting the side walls of the tank or trough which terminate at the upper edges of the intermediate sections. After the material has sutliciently set the intermediate sections are removed, and the spacer blocks 33 likewise removed if required. The retaining members 34, which are preferably of suitable screen material like the member 30, are then deposited upon the upper edges of the side walls just constructed, and the space between the member 34 and the upper edges of the outer and inner shell sections filled with cementitious material indicated at 37. The outer and inner shell sections are then removed leaving the tank complete with a dead air space between the vertical walls and the closure portion 37.

The various mold units may be cheaply and strongly constructed and the parts readily separated for shipment or storage or to enable the tank or trough to be erected in any required locality, or a plurality of the tanks erected in close proximity, the mold units beingadapted for use repeatedly, as will be obvious.

The spacer members 31 may be in the form of hollow brick represented at 38 in Fig. 6, and the base portion 36 may likewise be in brick-like form, as shown in the same figure.
